Embodiment 1
[0024] (a) A vacuum reaction chamber 1 is set and two opposite water electrodes 2 are installed in the tank, and a glass hexagonal discharge boundary 3 with a thickness of 2.4mm is set between the two water electrodes;
[0025] (b) offer gas inlet 6 on the wall body of described vacuum reaction chamber 1, and fill the mixed gas of argon and air into the vacuum reaction chamber;
[0026] (c) installing a hollow spiral tube heating coil in the vacuum reaction chamber 1, and heating the temperature of the water electrode to 353K;
[0027] (d Discharge conditions: voltage frequency 53kHz, voltage amplitude 4.3kV, air gap pressure 0.5Pa, argon content in the mixed gas in the air gap is 90%, discharge produces plasma photonic crystals with three quadrilateral structures nested. figure 2 one Figure 5 A schematic diagram of a plasmonic photonic crystal with three nested quadrilateral structures produced in this example. Figure 4 Middle: A is the structure diagram of the plasma ph...
